Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 8; Raggi anali molli: 9 - 10; Vertebre: 38. Can be differentiated from Pseudecheneis sulcata in possessing a longer pelvic fin, reaching base of first anal fin ray (vs. not reaching), from Pseudecheneis crassicauda in having longer pectoral fin, reaching origin of pelvic fin (vs. not reaching); from Pseudecheneis serracula in having a shorter adipose fin base (length of adipose fin base 125-166.7% in length of anal fin base vs. larger than 200%); and from Pseudecheneis sympelvica in having separate pelvic fins (vs. fused); from other congeners except Pseudecheneis immaculatus in having a long caudal peduncle (27.5-35.8% SL vs. 20-4-28.3); further from other congeners except Pseudecheneis stenura in having deeper forked of caudal fin, the shortest ray of caudal fin circa 50% of longest ray (vs. 75%). Differs from Pseudecheneis immaculatus in having shorter pectoral fin (27.1-30.6% SL vs. 29.4-38.3), and having yellow spots and patches on the body (vs. lacking); from Pseudecheneis stenura in having a saddle patch at dorsal fin origin (vs. two ovoid, isolated yellow patches on lateral of dorsal fin origin) and further in having shorter head length (head length 14.9-18.6% SL vs. 20.1-23.7, postorbital head length 4.5-5.9% head length vs. 8.5-11.4, body depth 73.9-112.2% head length vs. 67.1-88.5) (Ref. 74729).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00260 - 0.01333), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
